LangChain - Fundamentals

What will this LangChain code print?

from langchain.chains import SimpleSequentialChain
from langchain.llms import OpenAI
llm = OpenAI(temperature=0)
chain = SimpleSequentialChain(chains=[llm])
result = chain.run('Translate "cat" to Spanish')
print(result)

AError: chains expects Chain objects

Bcat

Cchat

Dgato

Step-by-Step Solution

Solution:

Step 1: Check the chains argument type
SimpleSequentialChain expects a list of Chain objects, but llm is an LLM, not a Chain.
Step 2: Predict the error
Passing llm directly causes a type error, so the code will raise an error.
Final Answer:
Error: chains expects Chain objects -> Option A
Quick Check:
SimpleSequentialChain expects Chains not LLMs [OK]

Quick Trick: Chains need Chain objects, not raw LLMs [OK]

Common Mistakes:

Passing LLM directly to chains list
Expecting automatic conversion to Chain
Ignoring type requirements
